Today, I tried out the Ble Bootloader from the Sdk examples.
As a central client, I'd used the »nRF Loader App« an an iPhone and also »nRF Mcp« on an Android Tablet.
I...
Hi,
from Keil uVision I need to debug/program nrf51822 in my application which uses 1.8 V. I guess nrf51 DK is not capable of doing this (it supports only 3 V targets). What...
Hi,
I have a reset issue when trying to set a delay greater or equal to 100 milliseconds using nrf_delay_ms(...). This only happens if I start my app timers (app_timer_start...
Hi,
I am trying to generate a 128Hz sine wave using the nrf_pwm library . First I tried this with SD110 enabled but ran into some problems that turned out to be a known...
Hi,
I'm going through the errata and a few of them look serious that the developer kit might be useless for some of us if we want to use it for any realistic testing (I...
